Quality

It is not just the big beasts of Chinese solar that are investing in aggressive expansion as high-efficiency wafer maker NorSun and tracker supplier GameChange Solar make big announcements. The New York company, however, may fall foul of President Trump’s America First trade mantra by opening production lines in the Far East.

At The smarter E Europe trade show, held in Munich in May, pv magazine was invited for another iteration of its Quality Roundtable events. Experts from manufacturing, project planning, finance and testing took the stage to inform the crowd on quality issues with modules, cables and inverters.

While PV module makers are attempting to get the best possible scores for their products on 3rd party tests, 3rd-party testing providers are also offering competing products to rank products. We look at what’s similar and what’s different in the tests.

Tests by U.S.-based PV Evolution Labs (PVEL) show that monocrystalline silicon and polycrystalline silicon PV modules produced by India’s Vikram Solar met and exceeded international quality and performance benchmarks.

In the run-up to pv magazine’s quality roundtable at Intersolar Europe, we look at a case where a production error resulted in cold solder joints in 5% of the solar modules across a 50 MW project portfolio. We consider how to come to an agreement with a manufacturer to replace modules in such a situation and how such a solution compares with a production audit before installation.

In preparation for the next pv magazine webinar “New approach for bifacial modules and yield expectations” on Monday 29 April, 2pm – 3pm (CEST), Andrea Viaro, head of technical service Europe, JinkoSolar and Lucie Garreau-iles, technical manager, EMEA, DuPont, in the following answer the questions by pv magazine on why create an alternative to the bifacial glass-glass-modules

What is your recommendation for investors when buying PERC modules? Can LeTID loss be completely recovered in the field? Can one be sure that there is no LID and LeTID in n-type cells? Presenters, Andrea Viaro, head of technical service Europe, JinkoSolar, Stefan Roest , CTO, Eternal Sun & Spire Solar and Paul Grunow, technology consultant, board of the PI Photovoltaic Institute Berlin AG answer these and other questions from a recent pv magazine webinar.

Mercom Capital Group’s Q1 2019 Solar Funding & M&A report has registered $2.8 billion in venture capital, public market and debt financing, up from $2.5 billion a year ago. Large scale project financing reached a record $5.58 billion across 43 deals and there were 18 solar corporate M&A transactions.

Often, it is not inverter faults that frustrate customers – such things happen – it is poor customer service. Here we look at the first of a series of cases that will be discussed at the pv magazine quality roundtable planned for Intersolar Europe, in Munich, which indicates what the industry must avoid in future.

Celebrating its one year anniversary during Solarex, Turkish monitoring and AI startup Solarify is looking to reduce false alarms from utility scale PV projects. Based out of an incubator in Ege University in the coastal city of Izmir, Solarify is on the hunt for international partners.
